Highlights
Liebherr H9X6 is a highly compact 13 liters 6-cylinder hydrogen engine. Still in development, this engine presents promising and encouraging results in terms of CO2 and nitrogen oxides (NOx) emissions. This 6-cylinder engine comes with port-fuel technology (PFI). PFI takes place at pressures below 20 bar directly into the intake system. The power density is 20 - 30% lower to that of a diesel engine due to air displacement effects. Port fuel injectors work in less demanding operating conditions which results in an easier design. This engine is the perfect sweet spot between decades of combustion engines development with our customers and advanced technologies to optimise the combustion of hydrogen.
